There seems to be little doubt now that colder weather will arrive for the weekend. The real question seems to be how much lake effect snow we'll end with on Saturday night and Sunday.

The air coming in is going to be cold, deeply cold in fact, but it's also going to end up being pretty dry.

Dry air normally limits the intensity of lake effect snow.

We'll be watching to see if the upper Great Lakes connect with Lake Ontario in the making of the snow bands down our way. Without that, heavy accumulations of snow would not be likely.

More about that as we start to develop a better sense for the direction of the wind this weekend in the next couple of days.
